Why no rows in sys.dm_os_cluster_* on Availability Group?

Running into some issues with failovers on an Availability Group with two nodes and a file share witness. I read a post and then I tried to get the HealthCheckTimeout value from sys.dm_os_cluster_properties and no rows are returned. My google skills are either not working well this morning or no one else has this problem. I was able to get the values out of the Failover Cluster Manager. I want to know why I get no rows out of the cluster DMVs when I do have a cluster. I am assuming I have something set up wrong.

SQL SERVER 2016 SP1 CU2
WINDOWS SERVER 2016

I also don't get any rows on 2012 SQL and Server versions.

Thanks in advance.

This dmv is for Failover Cluster Instance also known as FCI and not for Windows Server Failover Cluster (WSFC).


These properties are used to set the values that affect failure
detection, failure response time, and the logging for monitoring the
health status of the SQL Server failover cluster instance.
